SIGNAL Fort AUTOMOBILES.

A lication filed September 1a, 1926. Serial No. 136,335.

My invention relates to signals for automobiles, and more particularlyto signals for use with closed automobiles. An object is to provide adevice of this character which may be readily operated by the driverfromhis seat without the necessity of extending I one of his hands fromthe side of the vehithe detailed description thereof, and the novelfeatures of my inventive idea will be particularly pointed out in theclaims.

In the accompanying drawings which'illustrate a practical embodiment ofmy invention,- I Y Fig. l is a rear elevational view of the deviceshowing it secured to a post of an automobile. Fig. 2 is a view insection on the line 2-2 of Fig. 1. Fig. 3 is a view in vertical sectionon the line '33 of Fig. 5. Fig. .4 is an elevational view of the innerside of the device. Fig. 5 is a view in vertical section on the line 5-5of Fig. 3. Fig. 6 is'a fragmentary View in section on the line 6-6 of 5.i Fig. 7 is'a fragmentary'view in section on the line 7-7 of Fig. 5.

Referring to the drawings, the numeral 10 designates an open-sided orU-shaped casing which is closed at the toploy a curved member 12. Thecasing 10 together with an angle strip 14 constitutes a support for thesignal. 'The strip 14 is secured to a post P of a closed automobile byscrews 16 passing through holes 18 in'one of the angle .members of thestrip 14. The other angle member of this strip is provided withtransverse slots 20 as shown in Fig. 4. Bolts 22 pass through theseslots and through holes in the inner wall of the casing 10. It Wlll beunderstood that the provision of the slots 20 is for the purpose ofsecuring the casing 10. in a vertical position regardless of vwhether ornot the post P is exactly in a vertical position or is in an inclinedposition.

. pivotally attached.

The signalling-portion of'the device includes an arm which consists of atubular'member 24 which at'its inner end is securedto a base member 26havinga rounded wall 28. Secured to'the base'member 26 isa trunnion 30adapted to rotate in two forks 32 secured within the casing 10' atopposite sides there.

of. i A hollow head member 34 is secured to' the outer end of thetubular member 24 and th s head member has slots or windows 36' in itsfront and rearsides. Within the member 34 there is an electric lightbulb 37 "held 1n a socket 38 carried by the outer member. of

the tubular. member 24. A wire40 extends from the socket member 38 to acontact member 42 insulatively mountedon the base member 28. ranged toslide on'a curved contact strip 44 insulatively mounted on the inside ofthe casing 10. The battery ofthe automobile is connected by a wire 46with the contact strip 44. The contact member 42 moves off the strip 44when the arm is in its down.- ward position. For other positions of thearm, the two contacts are in engagement so that the lamp is lighted bycurrent from the battery. In order to releasably hold the The contactmember 42 is arsignal arm in different outward positions,

the outside of the rounded wall 28 is provided with depressions 48adapted to receive a spring-pressed ball 50' carried by the curved topmember 12. The base member 26 opposite the rounded wall 28 carries a lug52 to which the upper end of a link 54 is The lower end of the link 54is pivotally attached tothe crank 7 arm 56 carried by a rotatable member58 mounted in a rounded opening formed in a casting 60, the member 58being held in said opening by a cotter-pin 62 as shown in Fig. 5.Therotatable member 58 contains a recess across which a pin 64extends asshown 1n Fig. 2. A rod 66 passes rotatably through a hole in the post P.The outer end of the rod 66 is reduced to a less thickness than that ofsaid recess and is provided with a holethrough which the pin 64 passes,the hole being larger than the pin so the'rod 66 so that the driver mayreadily p v 0 operate the signal device.

that the device will function regardlessof A handle I j The operationand advantages of m invention have already been largely set torth. Thesignal arm is normally housed in the casing 10 in depending position asindicated zit-24L in Fig. 1-." l/Vhen thedriver wishes to signal, heturns the handle 68 thereby. bringing the signal arm into desiredoutward. positions such as indicated at 24- and 24 in which positionsthe arm-is temporarily held by the ball 50. An important advantage ofmyinvention consists in the fact. that when not in usefor signalling,the signal arm is housed in the casing 10 with no outstanding portionto'confuse persons who arerelying on'the signal as an indication of: themanner in which the automobile is. to be. driven. Another advantageconsists in the fact that the device. may bereadily attached to a post.

of any make of automobile regardless of the size. or inclination of thepost. It is apparent that the angle strip. 14 maybe'placed Witheitherend up. It is, therefore, pos-' sible to place the strip 14 so'that itsoutwardly ext-ending fiange will project from the middle portion of theinner wall of the casing 10 or to place it so that the outwardlyextending flange Will project from near the edge of such wall. My devicecontains no gears, pinions or racksyand hence the expense of cuttingteeth on such device is avoided.

I claim:

A signal for automobiles comprising a right angle strip one of Whoseangle memhers is adapted to be secured to thefront face of a corner postof the automobile and the other of whose angle members containshorizontal slots, asupport adjustably at;-

tached tosaid angle strip by, means of said: slots, a signal arm pivotedto saidsupport and ada-ptedto lie adjacent and parallel to the latter,and connections extending from said arm to the inside of the automobilewhereby said arm maybe swung into outward position.

In testimony whereof I hereunto afiixmy;

signature.
